BED-FRAME.

Specification of Letters Patent.

Patented Sept. 18, 1917.

Application led March 29, 1916. Serial No. 87,442.

To all 'whom t may concern:

Be it known that I, VILLIAM L. FREDER- ICKS, a citizen of the United States, resident of Minneapolis, county of Hennepin, State of Minnesota, have invented certain new and useful Improvements in Bed-Frames, of which the following is a specification.

In a certain type of bed frame angle bars are used for the ends of the frame and frequently the vertical flange of the end rails warps or buckles under the pull of the bedsprings thereon.

The object of my invention is to provide a means for distributing the strain on the end rails by bracing them and thus avoiding the buckling or bending of the flanges from their normal plane, and a further object is to provide such a bracing means that will not be displaced or lost when the bedframe is moved or shipped.

The invention consists generally in various constructions and combinations, all as hereinafter described and particularly pointed out in the claims.

In the accompanying drawings forming part of this specification,

Figure 1 is a transverse sectional view of a portion of a bed frame embodying my invention,

Fig. 2 is a plan view of the same,

Fig. 3 is a detail sectional view showing the manner of mounting the bridge in the end rail of the frame.

In the drawing, 2 represents the side rails of the frame having castings 3 at the ends.

thereof secured to the vertical flange 4 of the end rail. The horizontal flange 5 of said rail has holes 6 therein for the connection of the coiled springs 7 of the spring fabric 8. To prevent the end rail from bending or buckling under the pull of the spring fabric thereon, I provide a truss bar 9 which is secured by suitable means to the vertical flange of the rail preferably at the point 10. Between this truss bar 9 and the flange 4 I interpose a bridge 11 which is provided with a seat 12 to receive the truss bar 9. The bridge 12 is preferably constructed of angle iron and is placed at right angles to the vertical flange 4 of the end rail and is secured to the horizontal flange 5 by suitable means, such as a bolt 13 and nut 14, which help support the bridge 11 and take up part of the strain thereon. The vertical flange of the bridge bears against the vertical flange 4, of the end rail, at the point 15 so that the strain is divided between two points. As the. bridge 11 is securely fastened to the end rail when the tension of the springfabricis applied to the end rail of the frame, the truss bar and bridge brace the end rail and distribute the strain so that there is no danger of buckling or bending said rail out of its normal position. y

The rear end of the bridge is preferably beveled to insure the contact of the point 15 with the flange. The angle bar rail has a curve in the angle at the junction of its flanges, as shown in the drawing, and if the bridge were made square at the end, the point 15 probably would not contact with the flange. In other words, beveling the end of the bridge insures the seating of the corner 15 on the vertical flange 4.

In various ways the details of construction herein shown and described may be Vmodified and `still be within the scope of my invention.

I claim as my invention:

1. A bed-frame having an end rail composed of angle bar material with a horizontal and a vertical flange, a truss bar having its end portions secured to said end rail, a bridge interposed between the middle portion of said truss bar and said angle bar, said bridge having its upper portion seated against the horizontal flange of said rail and secured thereto, and its rear portion bearing against the lower part of the vertical liange of said rail for transmitting the strain of the truss bar thereto.

2. In a bed-frame, the combination, with an angle bar end rail having a horizontal and a vertical flange, of a truss bar secured at its ends, a bridge interposed between the middle portion of said truss bar and said end rail and seated against the under surface of the horizontal flange of said rail, the rear end of said bridge being beveled and having its lower edge in Contact with said vertical flange below the middle portion thereof.

In witness whereof, I have hereunto set my hand this 24th day of March 1916.

WILLIAM L. FREDERICKS.
